I've been following this back-and-forth for a while. Yes, I think it's
a good idea to use the root account as little as possible. Myself, I
use sudo in the overwhelming majority of cases.

But I learnt the hard way that sometimes it's a good idea to keep a
root account (with a corresponding password!) around.

When the system boots and the root file system is corrupt (or a
similar early-boot problem happens), you find yourself staring at
a message more or less looking like that:

  Please enter your root password to start a rescue shell:

(message is from memory, but you get the -uh- message).

This was shortly after Debian convinced me that having a root password
is The Evil Itself.

Duh.

I'm wiser now.

(Yah, there is a workaround for that: a rescue disk, and that's how
I got myself out of that, but hey).

Of course: no remote login as root (sshd_config). Use sudo in normal
life (it's more comfortable, anyway). All that. Use a hard-to-guess
root password (pwgen -n 16, for me).

But. A root password doesn't make your system more insecure (unless
it opens up one more remote access). And sometimes, just sometimes
you wish you had one :-)

Cheers
